JOHN B. VARING, OF NEV YORK, N. Y.

PULVERIZING-MACHINE.

SPECIFICATION forming part of Letters Patent No. 357,434-, dated February 8, 1887.

Application filed September Q8, i885.

.To all whom, it may concern:

Be it known that I, JOHN B. VARING, of. New York, in the county of New York and State of New York, have invented a certain Improvement in Pulverizing Machines, of which the following is a specication.

My present improvement is especially intended for use in pulverizing material ina wet state. It is also particularly applicable in many respects to the concentration and amalgamation of precious metals set free by pulverizing material containing the same.

I will describe a machine embodying my improvement, and then point out the various features of the improvement in the claims.

The accompanying drawings illustrate a machine embodying my improvement.

Figure l is a vertical section of a machine, taken in a plane coincident with the center of shaft, but showing the shaftand certain other parts unsectioned. Fig. 2 isa section of the machine, taken at the plane ofthe dotted line x of Fig. 1. Fig. 3 is a section of the machine, taken at the plane of the dotted line y y, Fig. 1. Fig. 4 is a transverse section of the chamber on a smaller scale,illustrating certain parts 'more fully than they areshown in the other figures. Fig. 5 is a detail view showing'the arrangement of certain guides employed in the machine. Fig. 6 is a side View, and Fig. 7 a sectional view, ofa certain scoop employed therein. Figs. 8, 9, and 10 are detail views showing the arrangement ot' certain propelling-blades.

Similar letters of reference designate corresponding parts in all the figures.

A designates a chamber, consisting, as here shown, of a circular body-piece, a, and two heads, a a2. Bolts a, passing through the edge portions of the heads a aL and the bodypiece a,secnre these parts together. The interior surface of the body-piece a is provided with a groove or rabbet, at, which preferably flares or increases diametrically toward the outer edge. In this rabbet is iitted aring of steel, a5, which externally flares toward one edge, so as to correspond with the rabbet,and internally is flat from edge to edge, or approximately so. This ring e5 fits snugly in the rabbet, and is held between the inner edge of the rabbet and a circular rib, a, which projects from the head a.' The bolts ai not only secure rby bolts or screws.

serial No. 176,342 (No mold.)

the heads c a2 and body-piece a together, but they also serve to secure the ring a5 in place. The head a is shown as quite tlat,except near the outer edge, where it is roundedinward toward the ring a5. At the center of this head a is an outwardly-tapering tubular portion, a7, through which the material to be pulverized enters the chamber. From the tapering portion aT a tube or hopper-chute, as, extends to a hopperwhence the material to be pulverized is fed to the chamber. The head a2 is approximately'tlat, but near the edge curves slightly inward, meeting thereby a portion, a, of the body-piece a, that curves transversely -inward to the inner end of its rabbet aand forms what may be termed a-gutter. This head a2 has a central outwardly-extending tubular portion, am. All partsof the chamber, except the ring a5, may be made of castiron.

'The chamberA is intended to rotate; hence the tubular portions el am of the heads a a* are externally cylindrical to serve as trunnions, and are supported in bearings a, comprised in standards a. The standards al'Z are shown as mounted upon supports c a, which are iliade in the form of boxesand secured thereto These box-like supports may be made of cast-iron.

The exterior of the body-piece a of the chamber A is adapted to receive a belt, G, which also passes around a pulley, H, on a rotary shaft, H', which is journaled in any suitable bearings and driven by any desirable motor. The chamber A and the shaft H rotate in the direction indicated by the arrows which are adjacent to them. The tube or hopper-chute e5 does not rotate with the chamber. It is here shown as formed in one casting with a water-inlet, a. This whole casting is mounted upon and secured to the box-like support als.

In the chamber A are pulverizing-rollers B, which travel in close proximity with the interior, surface of the ring a5. These rollers, as here shown, are propelled by rollers C. Iv have shown three ofthe rollers B and a correspending number of the rollers O. I do not,

however, Wish to be confined to any particu-V lar number. A carrier, D, is combined with the rollers B C and aflixed to a shaft, E, so as to be carried around by the latter., It maybe keyed or similarly fastened to the shaft 'and Ico collars a a, secured by screws to the shaft AE, prevent any movement of it lengthwise of the shaft. The :motion of the carrier causes the rollers B C to revolve within the chamber. As the rollers B C revolve within the chamber they rotate on their axes.

The carrier D consists. essentially, of two plate-like portions, d d', and an intermediate hub-like portion, d. lt may also comprise connecting portions d, It can be made of cast-iron in one piece. 'The plate-like port-ion d of the carrier is shown as made in the form of a circular disk; but the plate-like portion d is of somewhat irregular form, consisting, essentially,of a central portion and three armlike portions extending therefrom.

The propelling-rollers C are arranged upon shafts c, which are supported by the carrier. In the example of my improvement which I have shown these shafts c are not intended to rotate within their bearings in the carrier, but the rollers C are intended to rotate upon these shafts. The rollers B are pulverizingrollers. They have no shafts. The propellingrollers C, during the rotation ofthe shaft E, force the pnlverizing-rollers B around the chamber. As soon as the pulverizing-rollers acquire sufficient centrifugal force they fly out close to the interior surface of the ring ci', and thereafter they travel around the same( In traveling around the chamber A the pulverizing-rollers B acquire a rotary motion and cause the propelling-rollers C also to rotate. The revolution of the rollers C of course tends to cause an outward movement of them through centrifugal force. This tendency is, however, more or less neutralized by the manner in which the said rollers C are rotated by the rollers B, because the latter act on them at such a point as to tend to force them toward the axis of the shaft E.

Both the rollers B and C may advantageously be made of steel. Vhen the portions d'd of the carrier are used, they will preferably be made arc-shaped, and arranged so that their concave sides will be toward the pulverizing-rollers B. They form guards and prevent the pulverizing-rollers from dropping down beyond the control of the propellingrollers C when the motion of the carrier ceases. The shaft E extends through the chamber A and the tubular portions a7 am of the latter. Where it passes through the tubular portion ai, a sleeve, al, extends inwardly from the tubular portion al to the collar ai".

The shaft E is supported in bearings e, comprised in standards c', erected on the basepieces als a,

On the shaft H pulleys HAZ are affixed. Belts I pass around the pulleys H2, and also around pulleys I affixed to the shaft E. The shaft E is thus rotated in such direction as to cause the carrier D to revolve in the direction indicated by the arrow which is adjacent to it. The motion imparted by the belts I to the carrier D is faster than the motion which the chamber A derives from the belt G. The' tendencyl of the chamber to acquire additional vspeed from the rollers B is resisted by the belt G. This does not involve a waste ofpower, however, because any power of rotation which the chamber thus transmits to the shaft H aids in rotating the shaft. The speed of the chamber may be varied by selecting a pulley, H2, of proper size.

In the lower part of the tube or hopperchute a8, and extending around the sleeve a, are guides a, which will direct material that is introduced through the hopper-chute into the chamber A beyond the fiuid inlet a, These guides, as here shown, consist of a plate. The top of the sleeve al, to the rear of this plate, is flat and covers the space back of the plate and above the tube.

The shaft E has connected to one end, by a suitable union-coupling, E', a non-rotary water-pipe, E2, and the shaft is hollow from the end which is connected tothe said water-pipe to about the middle of its length, so that water mayflow into it from said pipe.

A branch water-pipe, E3, is connected to the water-pipe E2, and'also to a nipple which communicates with a water-conduit, ai, which is formed in the support am. The water-inlet a'I5 is in communication with the water-conduit a, and from the latter water can pass lto the water-inlet au. A packing, a, consisting of a piece of dexible tubing tted into flaring recesses in the top of the support a and at the bottom of the water-inlet a, makes a tight joint between the parts.

The water-pipe E3 is shown as provided with a cock for controlling the passage of water through it. The flow of water through the pipe El may be similarly controlled. The water which passes through the water-inlet ali entersl the tubular portion (1.7 of the chamber A close to where thematerial to be pulverized is introduced, and it prevents said material from adhering. Passing beyond the tubular portion a7 of the chamber A, the material and water fly out toward the circumferential portion ofthe chamber. The material will accumulate there to a thickness which will make it coincident with the inner surface ofthe ring a5 and substantially to the line a2", Fig. 1.

The circumferential portion of the chamber is provided internally with a number of lugs, er, extending toward the center of the chamber. They cause the material to be pulverized to revolve with a speed corresponding to that of the chamber.

The material to be pulverized is reduced principally between the pulverizing-rollers B and the ring 0.5, but also more or less between the pulverizing-rollers and the propelling-rollers C. It may bc aided in its passage between the pulverizing rollers and the rings by oblique propelling -blades pm, arranged on the edge of the plate-like portion d of the carrier D. The form of the propelling -blades and their arrangement are shown more clearly in IKO Figs. 8, 9, and IO. The water flowing into the shaft E passes out through radial holes e2 into ports or passages dt, extending radially within the plate-like portion d of the carrier D. From the passages d4 it passes into cavities in the shafts c and escapes from radial extension'sof these' cavities into cavities c' in the central portions of the rollers C. The water reaching the rollers C passes away between theserollers and theirrshafts. and flowing out at both ends of the rollers C not only lubricates the shafts, but prevents the admission of grit.

A disk, F, which may advantageously bel :made of steel, is fastened to the carrierD close to the platedike portion d. It is shown assecured in place by the collar c, and extends to within a short distance of the interior of the chamber A. An annular piece or ring, J,

vwhich may also be advantageously made of steel, is arranged close to the disk F, but is farther than it from the carrier D. This ring J is fastened to lugs au* (here shown as six in number) extending from the interior of the chamber. Its outer edge is closer to the interior of the chamber than is the outer edge of the disk F. The ring overlaps the disk F but slightly. The space between the ring and disk is very small.

The lugs a may be east integral with the chamber A. They have notches in which the ring fits and is held. The ringis made of two semicircular portions. One section is slipped into its place within the notches of three of thelugs a. Then the other section is inserted into the notches of the three other lugs a. It will be necessary to spring or bend both sections somewhat laterally to get the last-inserted section into its place. Then the lastinserted section is in place, its ends abut against the ends of its fellow. Then beth sections are turned around until their ends arewithin op posite lugs c. The ends of the sections will thereupon be prevented from passing one another, and the sections will be secured in place.' This may be best understood by reference to Fig. 4.

Mercury may, when desirable, be used in the gutter aJ of the chamber A in sufficient quantity to almost reach to outer edge of the ring J when distributed around the gutter by centrifugal force generated by its rotation with the chamber.

Pulverized materialpassing beyond the ring c5 is caused bythe high velocity of the disk F to be thrown outward with great force into it and to pass over ythe surface of the mercury, and any valuble metal which may be comprised in it will thus be thrown into the mercury and amalgamated or concentrated on its surface.

terial which has passed under the ring J is allowed to remain in a state of rest, except for its revolution with the chamber.

Water in the chamber may pass between the disk F and ring J and into the gutter a9 inward of the mercury, or, in other words, nearer the center of the chamber, thereby causing a suflicient disturbance offthe mercury to insure amalgamation where amalgamation is possible.

It will be desirable in many instances to prober of holes, k', with which the scoop K is provided near its upper edge. The lower end ofthe scoop K is -pivotally connected to one end of a link, K2, which at the other end is pivotally connected to an arm, t, which is affixed to a rock-shaft, L. The rock'shaft L isjournaled in the clamp K and extends through the tubular portion thereof, from which extends the arm supporting the pivot a. The rock-shaft L has affixed to it another arm, t. This arm t may be fastened in any desirable position by means of a pin, t2, which passes through it and enters one of a series of holes, t3, which are arranged in t-he arc of a circle in the clamp K. By shifting the rock-shaft the lower end of the scoop may be moved farther from or nearer to the interior of the chamber A. In the scoop, preferably, are slots Ict le, the lower edges of which may be bent or extended inward. The upper edge of the scoop catches the matter which is close to the interior ofthe chamber, or, in other words, farthest from the center ot' the chamber, and removes it therefrom. scoop through the slots of the scoop, and the remainder passes off the lower end of the scoop. The matter is thus frequently put into a state of commotion and perfect concentration and amalgamation are facilitated. i

In Fig. 3 the scoop is shown asV supported in adifferent position on the annular ring from that shown in Fig. 6, in order to conduce to a clear illustration of the parts shown in Fig. 3.

M is a pipe extending into the chamber A close to the ring J. so that it may catch the matter which rotates with the chainberA. It is supported by a standard, ad, which is erected upon the support c, and provided with a vertical slot, a, through which passes a screw, ai, fastened to the pipe. A nut, c3", applied to the screw a- 29 outside the standard am, provides for clamping the pipe in different vertical positions. When only the water and waste matter are to be removed, the pipe is lowered but when con- Its upper' end is turned IOO IIO

Some of the matter escapes from the centrated material is to be taken oft' the tube is elevated more. The position of the tube regulates the depth or thickness of the layer or stratum of water and pulverized material.

The matter taken off by the pipe M is delivered into a chute, m, arranged in the support au. rlhe chute m has pivotal] y attached to it a swinging section, m', that works over flanges arranged at the lower end of the chute fm, and made concentric with the pivots on which the said section m swings. A rod, M2, pivotally connected to the section m', provides for swinging the said section into communication with a deliverychute, N, in a base-piece, N', designed to carry off the water and waste matter, or after the valuable material has been concentrated or amalgated, into communication' with a chute, N, in said base-piece, designed to carry away such concentrated or amalgamated material, the pipe M having been properly adjusted for removing such material from the chamber A. The base-piece N has the supports a13 a mounted upon it, and it may be made of cast-iron.

In the base-piece N below the chamber A is a tray, a, which inclines in both directions toward one corner. The body-piece a of the chamber A is provided with a removable screw-plug, am. This plug may be removed when that portion of the chamber A containing it is immediately above the tray a to allow the mercury, with the concentrated and amalgamated material, to pass out.

The use of the water may be omitted at times, or altogether, if desirable. Instead of water, oils or chemically-prepared liquids may be used. W'llere dry products are desired, air or other gas may be circulated, instead of liquid, through the machine.
